The beast was discovered while they were carrying out a controlled explosion

Video footage taken by one of the crew pans down the snake's enormous body - which measures one metre in diameter.

After making the frightening discovery, the workers chained the animal to a crane and later lifted it up to reveal its yellow spotted under belly - a move which was criticised in the comments when the clip was uploaded to YouTube.

It's claimed the builders killed the snake rather than leave it in its natural habitat but this has not been confirmed.

Others believe the animal may have died in the explosion, possibly being hit by falling debris, as its head appeared flat in the video footage.

One user wrote: "I'm not sure this is real, but if it is, shame on these people for killing it! A snake that big has probably been alive for a very long time now, just to be killed for a few pictures? What a waste."
